Question

A train cross a 270 m long bridge at the speed of 54kmph in 30 second.how much the length of train?

Answer 1

Answer:

Given,

length of the bridge=270m

speed of the train=54kmph

time taken to cross the bridge=30sec

54kmph=54000m

(54000)(30)/270

1620000/270=6000m

1000m=1km

6000m=6km

so, the length of the train is 6km
